DesignTech Systems Interview Questions, Process, and Tips

Casting is a manufacturing process in which a liquid material is poured into a mold and allowed to solidify.

• Types of casting include sand casting, investment casting, die casting, and continuous casting.

• Sand casting involves creating a mold from sand and pouring the molten metal into it.

• Investment casting involves creating a wax pattern and coating it in ceramic before pouring in the molten metal.

• Die casting involves i...read more

Cylindricity is the roundness of a cylinder while runout is the deviation of a rotating part from its axis.

• Cylindricity is a 2D measurement while runout is a 3D measurement.

• Cylindricity is measured using a cylindrical gauge while runout is measured using a dial gauge.

• Cylindricity is important in manufacturing cylindrical parts while runout is important in ensuring smooth rotation of parts.

• Examples of cylindricity inclu...read more

Runout is the deviation of a rotating component from its ideal axis, while total runout is the maximum amount of runout in any direction.

• Runout is a measure of how much a rotating component deviates from its ideal axis

• Total runout is the maximum amount of runout in any direction

• Runout can be caused by factors such as manufacturing defects, wear and tear, or misalignment

• Total runout is important in ensuring that a rotat...read more

Curve mesh and curve through mesh are two different methods of creating curves in UG NX software.

• Curve mesh creates a curve that passes through the mesh points, while curve through mesh creates a curve that follows the mesh points.

• Curve mesh is useful for creating curves that need to pass through specific points, while curve through mesh is useful for creating smooth curves that follow the mesh.

• Curve mesh can be create...read more

Hot and cold chamber casting is a process used to cast metals with different melting points.

• Hot chamber casting is used for metals with low melting points like zinc and magnesium

• Cold chamber casting is used for metals with high melting points like aluminum and copper

• In hot chamber casting, the metal is melted in the casting machine itself

• In cold chamber casting, the metal is melted in a separate furnace and then transf...read more

The commands predominantly used in NX are modeling, drafting, and assembly commands.

• Modeling commands like extrude, revolve, sweep, etc. are used to create 3D models.

• Drafting commands like dimensioning, annotation, etc. are used to create 2D drawings.

• Assembly commands like mate, align, etc. are used to assemble multiple parts into a single product.

• Other commonly used commands include simulation, rendering, and analysis...read more

Manufacturing can be broadly classified into four types.

• Mass Production - producing large quantities of identical products

• Batch Production - producing a specific quantity of a product in batches

• Job Production - producing custom-made products as per customer's requirements

• Continuous Production - producing products without any interruption
